The materials of plastic drums are mostly blow molded and injection molded from plastics such as polyethylene and polypropylene. Shanghai plastic products are chemical, pesticide, medicine, food, hardware, electronics, electromechanical and other industries. But sometimes the plastic bucket will be deformed. Today we will study and analyze the reasons:
The reason why the plastic barrel can be deformed is that the plastic bucket wall thickness control point is less, causing the barrel body to be uneven, so it is looser when formulating the standard of the plastic barrel. The two-point wall thickness of the symmetrical case is allowed to be in the range of 2:1. within.
In this case, the plastic bucket with uneven wall thickness of the bucket is often qualified when it is subjected to anatomical analysis. In actual use, the plastic barrel is deformed because the thickness of the barrel wall is too large.
